I'm attaching a video that shows part of the problem, i need to use Box2D because its part of a project in University.

Also, here's the movement code:

void Player::move(sf::Time time)
{
        b2Vec2 boxPos = getBox()->GetPosition();

        auto dt = time.asSeconds();

        getBox()->SetTransform(boxPos + b2Vec2(VELOCITY * dt, 0.0f), getBox()->GetAngle());
        setPosition(sf::Vector2f(boxPos.x * 30, boxPos.y * 30));
}

Hi everyone!
i am building the game 'Geometry Dash' using Box2d (in c++ and SFML of course), and my the movement of the player is very choppy.
I tried everything- erasing the Box2d part in the code, playing around with the framerate, using m_window.setVerticalSyncEnabled(true); , different ways to use the setp() func and different ways to handle time, but nothing seems to help!
In addition, i noticed that the Behavior of the player is different when i run the program on different computers, but its never smooth.
Does anyone have any idea what might be causing it? i'll take any advice at this point.
thanks!
David
